ROTARY MEASURING AND SELF-CLOSING l-"AUCET.

SPECIFICATION 'forming part of Letters Patent No. 272,176, datedFebruary 13, 1853.

Application filed September 29,1879.

To all whom it may concern Be it known that I, THEOPHILUS WEAVER, of thecity of Harrisburg, county of Dauphin, and State of Pennsylvania, haveinvented a new and useful Improvement in Rotary Measuring and Self-Closing Faucets, which improvement is fully set forth in the followingspecification and accompanying drawings, in which- Figure 1 is aperspective view of my'sai'd faucet, showing one part of the casing insectional view and parts of the stop-clutch and of the induction-pipebroken away. Fig. 2 is a perspective front view of my faucet with partof the winch and part of the gate broken away. Fig. 3 is a sectionalview of the index and stop wheel and its friction devices. spective viewof the measuring-valve. Fig. 5 is a front view of the stop-clutch. Fig.6 is a perspective view of the exi t-pipe stopple, shown detached fromthe gate. Fig. 7 is a perspective view of my faucet with the winch,index-w heel, and clutch removed and part of the casing broken away.Fig. 8 is a perspective view of the same with the gate also removed andthe casing partly broken away to show the piston in front of the valveand over the eductionport. Fig. 9 is a perspective view of the gate.Fig. 10 is a perspective view of the piston. Fig. 11 is a front view ofpart of the rear section of the casing, showing the valve insertedtherein and the position of the ports partly-by Fig. 12 is a perspectiveview of my strainer.

The object of my invention is to furnish a faucet that will readilydeliver from a cask or other reservoir various grades of molasses,

oils, and effervescent liquids-in the two firstnamcd articles measuringthem and in the lastnamed checking the issue of the liquid, and for allthe kinds of liquids named answering as a self-closing and safety faucetand as a tellingfaucetand one that can be cheaply manufactured, itsparts being almost entirely capable of being finished by commonlathe-work.

The principal novel and useful features of my improved faucet are:First, a measuring or cut-off valve arranged longitudinally in theinduction-pipe and projecting at its front end into the faucet-chamber,and by its body or head barring the passage therein between the Fig. 4is a perround hub of the piston, located centrally in -thefaucet-chamber, and the circular Wall of strike on the sweep of thepiston to allow it to pass by the valve-head at the end ofeach'rcvolution of the piston; second, a radial full-sweep pistonmounted on its actuating-shaft directly,

and revolving by pivot motion in the axis of a circular faucet-chamber;third, the arrangement ofthe induction and the eduction ports nearlyopposite--one in the front end and the other in the rear end of thecasing-that the valve may bear against the rear side of the piston-sweepwhile the exit-port is closed thereby; fourth, a special adaptation ofthe stop-clutch, that its'use may be omitted at will, while theindex-wheel is allowed to continue its operations without being stoppedat each revolution, when the quantity drawn is a multiple of thatdenoted by one revolution of said wheel and it is preferred to drawwithout stopping at intervals; fifth, an improved spring gate andstopple for closing the eduction-spout, after it is closed internally,to stop the dripping of clinging sirup in said spout after the drawingis stopped; sixth, an improved attaching-joint for the strainer.

In all the views of both plates of the drawings similar letters denotesimilar parts.

A represents the wall of the major section of the casing. A is the frontend of the same, and has centrally on it the journal-box A in which thepacking T is held about the neck '1, between the journal-shoulders Z Zon the piston-shaft T X.

B represents the minor section of the casing, it being also the rear endof it,-and hason it the wrench-socket B in the staple B, which ismadeangular that it may be caught by a wrench to screw the induction-pipe Pinto a cask-head. Said pipe is located aside from the center of saidend,and on the upper part ofit, to secure a down-grade flow of the liquidfrom the cask into the faucet-chamber, and. proper filling of the latterwhen the former is nearly empty. In the taper end of said pipe P is-aprojection, H, in which is guided the stem H of the cut-off valve 0 D.

IOC

11 represents a spiral spring,which sets about said stem against saidprojection at its foot, and at its other end againstthe body D ofthevalve, which it actnates, holding it press d against the front end ofthe casing, and when tripped holdin g it pressed against the rear sideof the sweep Q, of the piston, as shown in Figs. 1 and S. The body D ofsaid valve is semi-cylindrical, and fills the transverse space betweenthe circular wall of the casing and the hub L of the piston, mountedcentrally in it, as shown in Figs. 7 and 11. The fiat side of said bodyis plat-ed parallel to the radius of the faucetchaniber; but it may bearranged as a secant to its circle, it being only essential that itclose the space between the wall A and the hub L. Saitbbody D is madelonger than the depth of the faucet-chamber, that, by resting with itstint side against the abutments F, about the inlet-orifice F, it mayrest with its convex side against the inside of the induction-pipe toresist canting or bending of the stem H when it is being tripped by thestrike Q on the sweep Q of the piston;

The sweep-piston is in form substantially as shown in Fig. 10, and islocated in the casing, as shown in Figs. 1 811(17. Its shat't T Xhas theactnating-winch E applied thereto by screw 8 and plate f. Said shat'thas the journalbossesZ Z thereon,which hold the packing between them.The boss Z may be omitted, and a corresponding ring may be formed in thetube A as one of the. bearings. Said shaft has on it the hub L, which isof length equal to the depth of the faucet-chamber, and it is part waycylindrical, and the balance of its body is extended at right angles toits shaft to form the cam-form sweep Q Q,which is also of the same depthas said hub, and is in form as shown in Fig. 10, it being mainly asector of the circle that inscribes the circular wallA of thefaucet-chamber, as shown in Figs. 1 and 7. The front side of said sweepQ Q is a plane, and is of more area than its rear side, as the strike Q,and its hind end,W'-, are cutaway obliquely, as shown. Said strike is somade that it may readily travel over the valve-head C, which is alsobeveled at U to favor its approach. The part W is squarely edged, thatit may serve as a scraper for the wall A. The hind end, W of the sweep Qis beveled, as shown in Fig. 10, to let the Valve down gently after itis passed by said sweep. The retreat in the sweep between the strike Qand the hub L is so made to clear the way for the ascent of thevalve-head C while being tripped, and to prevent gorging by a littleremnant of the undischarged liquid, which thus escapes from its corneredplace to the induction side of the valve, and prevents forcing thejointsof the casing and straining its works. For the same reason theeduction-port G is arranged nearly opposite and near to theinduction-port F, as well as that the valve may bear against the sweepwhen it is over the eduction-port.

The faucet-chamber is the space inclosed by the circular wall Aand theends A and B of the casing, and it has the induction-portF and theeduction-port Gin the rear and front ends, respectively, as describedand as shown in Figs. 8 and 11, theport F communicating with theinduction-pipe P and the port G communicating with the ednction-pipe Gon the front end, A. The capacity of said chamber is equal to one gillplus the solid contents of hub L and sweep Q, plus a remnant forcornering, as the piston can only discharge at each revolution whatis inthe chamberin froutof it-immediately after the valve has come toposition ofl' the sweep Q. and is set as a cut-off or bar, thus causingthe liquid to pass out at the eduction-port the balance of itsrevolution, which at its completion passes a small cornered remnant;back again in endless circulation. At the same time the piston iscompelling the measured and cut-off portion to go out of thefancet-chamber at the ed notion-port an equal portion is again replacedin it by drawing on the liquid from the reservoir to till the vacuumproduced by the pistons advance. At the completion of each revolution ofthe piston and of each full measuring, the cut-0d valve is againautomatically tripped and set as a bar by the advance of the sweep Q,and the discharging is repeated, as before, by a positive operation. Ifthe rotation of the piston be stopped immediately after the valve isfully tripped, before it has come off the sweep Q, the latter body willstand over the eductionport G and close it, as shown in Figs. 1 and 8,theinduction-port F being then only partially covered. Theactuating-winch E is so applied to the shaft of the piston that itshandle M may be down when the said port- G is closed, as shown in Fig.2. \Vhen said parts are in said positions there will be no escape ofliquid from the reservoir drawn on by way of the faucet; but if theliquid is viscid there may be a little dripping at the mouth of theeduction-pipe G, on account of a portion adhering therein immediatelyafter drawing. The spring-gate P R, made as shown in Fig.9 and appliedand operated as shown in Figs. 2 and 7, is added to the faucet to arrestsaid dripping. Said gate is made with a box, K, for the insertion of aspiral spring, I, which sets in it above the attaching screw or bolt k,by which the body K is held applied with its face It against thestandard m. Said screw or bolt is inserted into said standard throughthe slot K, which allows the gate to move vertically when operated, andthe face R is so made to allow it to revolve about said screw that whenthe conical or oval stopple b d on its foot 19 is removed from the mouthof the pipe G it may be set back out of its way, as shown in Fi 7. Saidstopple may be made detachable and in form as shown in Fig. 6. Theobject in making said stopple conical or oval is that it mayreadtly findits central place in the mouth of pipe G, which is reamed outcorrespondingly, thus making a liquid-tight stopple without the use ofthe usual packing,

I leather, or fibrous matter, which has heretofore been employed, withsome disadvantage, for this purpose. On said eduction-pipe G there iscast a seat, L, (shown in Fig. 7,) on which is attached by screw or studthe indexwheel 4 tin position as shown in Figs. 1 and 2. Said wheel hasin its recessed hub the spiral spring N held crowded therein by theplate a, under the head of the attaching-screw N, to hold the wheel byfriction between the intervals of its engagement. Said wheelis notchedroundlybetween the unpitched teeth 1' and index 1? thereon, audits hubis provided with the lug N, as shown in Fig. 3.

On the winch-wrist E is the knuckle e, which is adapted and arranged tocommunicate with one of said notches, and pass said wheel one-eighth ofa revolution at each turn of the winch Ethat is, for a faucet of onegill capacity one revolution of the eightnotched wheel shown occurs whenthe drawing has amounted to one quart. The indicatort then points upwardand the winch E stands down, as shown in Fig. 2. The sweep Q of thepiston, when the indicator and the winch are in the positions stated, isover the exit-port G, as shown in Fig. 8. When said parts are in saidpositions the stop-clutch W V automaticallycatches the lug N on theindex-wheel and locks it both ways by said lug N acting as a detent inthe clutch-notch R and the knuckle e acting as a detent in a notch ofthe index-wheel. Said stop-clutch is provided with the eye R throughwhich it is swiveled on the piston-shaft, and it is kept thereon by thewheel W V,which is in front of its flange L". The winch E may thereforebe removed for shipment without disconnecting or dropping off otherparts. If desired, the faucet can be run without stopping at intervalsby throwing the stop-clutch over center and out of gear, as indicated inFig. 2. Said clutch is not only a telling device by stopping themachineat a certain point, thus announcing the drawing and the closingof the port internally, but it also acts as a check device to resistpressure from the reservoir, which would otherwise move the piston andopen the exit-port, and in case the liquid was fermenting oreffervescent the valve P R might also be forced open, and thusleakagewould occur.

Several details of the construction of my faucet may be modified inpractice, which need not be shown to be understoodas, for

examples, first, the circular wall Aof the'faucet-chamber may be cast aspart of the rear section of the casing, the present lid of the chamber,and then the front section will be the lid of the same; second, the saidlid may have formed on it a skirting or standard around its edge tore-ent'orce it and cap the other section, that the parts,when joined byscrews g, may better resist stress; third, the sweep of the piston maybe relieved of part of its bulk by recessing its body, as indicated 1 atW Fig. 10; fourth, the knuckle e on the wristEof the winch maybe cast aspart of the face-platef, which may also have cast on it a square lug toseat it partly in the eye of the winch; fifth, the register and stopdevice may be made to arrest the movement when a pint has been drawn,instead of when a quart has issued, in two ways-either by adding anotherlug on index=wheel 7', similar and opposite to lug N, or the knuckle 0may be duplicated to pass two teeth, 0' a", of index-wheel at eachrevolution of the winch.

My improved strainer for insertion into'the end of the induction-pipe Phas the usual meshed head, L which is provided with a novel and usefulattaching-shank having in it the hook or return-slot h, which, inconnection with the lug H, formsa sort of bayonetjoint, the object ofwhich is that when the pipe P is being inserted into a cask-head thestrainer may not accidentally drop off into the vessel; or when thefaucet is being removed from a cask it may not be left buried in thefooting of sirup in it, and thus be lost, as now frequently occurs.

1 am aware that the foregoing bayonet-joint may be modified, asaraisedteat or lug on the inner side of the inlet-pipe may be employed to catchin a suitable depression or groove on the strainer-tube to hold it.

I am also aware that the principle or plan of construction of my faucetmay be used in meters generally, in pumps, and other machinery as well.I therefore do not limit my invention to faucets exclusively.

I also know that a faucet is extant having its inlet and outlet portsboth located adjacen'tly in the rear end wall of the meter-chamber, thatthe piston may cover both ports at a certain interval during eachrevolution, and that such arrangement, however, is impracticable, asgorging occurs a moment before both ports are covered, thus forcingliquid out at the joints of said chamber; and another difficulty is thatthe liquid acts to press the piston from its seat, and it must thereforecause leakage at the discharge-spout, especially when the parts are wornsomewhat,-unless the lid is sprung on the chamber, and pressure is thusobtained in the spring of the lid to hold the piston toits seat on theports, which of course causes the faucet to work hard. All thesedifficulties I entirely avoid by my new and different construction andarrangement.

Havingthus fully described my invention, I here add what I desire tosecure by Letters Patent of the United States, expressed in claims asfollows:

'1. The valve arranged longitudinally in the induction-pipe andprojecting at its front end into the measuring-chamber, and therein byits body barringthe passage between its circular wall and the circularhub of the piston located centrally in said chamber, and by contact withthe piston producing the intermitted cut-off, substantially as setforth.

2. The segmental piston having its hub and actuating'shaft centrallyarranged in the circular meter-chamber, and having the edges of -itssweep beveled or inclined to the plane of its revolution for trippingthe valve arranged at right angles to said plane, substantially as setforth.

3. In a liquid-meter, the arrangementof the inlet and the outlet portsin the opposite end walls of the meter-chamber, and with a partialoverlap transversely relative to each other, that the outlet-port may beclosed by the front side of the piston, and held seated over saidportopening by the pressure of the valve and the liquid acting againstthe opposite side of the piston, substantially as set forth.

4. The interlocked arrangement of the indexwheel and the actuating-winchby the gravitating stop-clutch swiveled to the pistonshaft, so that therotary movement is stopped both ways, substantially as and for thepurpose set forth.

5. The index-wheel r 2?, provided with the lug Non its hub, and with thefriction attachment consisting ot'the spring N and screw N, incombination with the cog e on wrist- E of winch E, and with thegravitating-clutch \V V,all arranged that the clutch may be used oromitted during the measuring, in the manner i set forth.
